Jacob's Well

Jacob's Well is a karst spring in Wimberley, Hays County, Texas, with an opening in the limestone surface roughly 12 feet wide. Water flows up from a vertical cave system that extends around 137 feet down before opening into horizontal passages.

Settlers in the 1850s used the spring water to run a sawmill, which formed one of the first structures in the community. This early use of the water helped establish Wimberley as a permanent settlement in the Texas Hill Country.

European settlers named the spring after the biblical well in Sychar when they discovered the clear water flowing from the limestone. Today visitors come mainly to swim and enjoy the natural pool, which has served as a gathering spot for cooling off across generations.

Between May and September, you need to book an online reservation to swim, as visitor numbers are limited. Plan to book several days ahead, especially on weekends and during summer months.

The horizontal chambers of the cave system stretch around 4,500 feet through an underground maze of narrow passages and open rooms. These hidden sections remain out of sight for regular swimmers and are accessible only to experienced cave divers.
